Two fundamental experimental tests of nonclassicality with qutrits
(Nature Research, 2013-07-10)
We report two fundamental experiments on three-level quantum systems (qutrits). The first one tests the simplest task for which quantum mechanics provides an advantage with respect to classical physics. The quantum advantage ...

Experimental fully contextual correlations
(American Physical Society, 2012)
Quantum correlations are contextual yet, in general, nothing prevents the existence of even more contextual correlations. We identify and test a noncontextuality inequality in which the quantum violation cannot be improved ...

Experimental implementation of a Kochen-Specker Set of Quantum Tests
(American Physical Society, 2013)
The conflict between classical and quantum physics can be identified through a series of yes-no tests onquantum systems, without it being necessary that these systems be in special quantum states. Kochen-Specker (KS) sets ...
